抗剥落剂对沥青及沥青混合料性能的影响研究

Research on Effect of Anti-Stripping Agent on the Performance of Asphalt and Asphalt Mixture

文章选取一种有机高分子非氨类抗剥落剂,研究了不同掺量的抗剥落剂对沥青和沥青混合料性能的影响,同时进行了沥青的三大性能指标试验与沥青混合料的水稳定性和高温稳定性试验。试验结果表明:抗剥落剂显著提高了沥青的低温性能,降低了沥青和沥青混合料的高温性能,但一定掺量的抗剥落剂能够显著提高沥青混合料的水稳定性,并得出了抗剥落剂的最佳掺量为0.2%。

In this paper,an organic macromolecule Non-ammonia anti-stripping agent was selected to study the influence of different dosage of anti-stripping agent on the performance of asphalt and asphalt mixture.At the same time,three performance indexes of asphalt andwater stability and high temperature stability of asphalt mixture were tested.The results show that the anti-stripping agent can significantly improve the low temperature performance of asphalt and reduce the high temperature performance of asphalt and asphalt mixture,but a certain amount of anti-stripping agent can significantly improve the water stability of asphalt mixture,and the optimum content of anti-stripping agent is 0.2%.
